我想使用apache poi在 private void readFromExcel() {
if (ContextCompat.checkSelfPermission(this, Manifest.permission.READ_EXTERNAL_STORAGE)
!= PackageManager.PERMISSION_GRANTED) {
Toast.makeText(this,"you dont Hve permission",Toast.LENGTH_SHORT).show();
return;
}
else
Toast.makeText(this,"YOu have permission",Toast.LENGTH_SHORT).show();
try (Workbook workbook = WorkbookFactory.create(new File(DOC_PATH))) {
Log.i(String.valueOf(this), "Workbook has " + workbook.getNumberOfSheets());
} catch (IOException e) {
e.printStackTrace();
}
}
文件中读写，但是我找不到文件
